Solar street light design

The design of the solar street light includes how to choose the battery, the design of the angle of the bracket, the design of wind resistance and the design of the solar controller. Each of these requires serious thinking. While considering, we need to combine local characteristics: local annual radiation and local daily average sunshine hours for analysis. Under normal circumstances, choosing two 12V100AH u200bu200bbatteries can meet the requirements of many regions. We mainly explain the design of the solar cell module bracket and the selection of the controller.

The design of the solar cell module bracket is to ensure that the solar panel can receive as much solar radiation as possible in a year, so it is particularly important to choose an optimal tilt angle. Regarding the issue of the optimal inclination angle of solar cell modules, there are many professional literatures that can be referred to. Based on the field, taking the Shenzhen area as an example, 16° is the most suitable inclination angle.

In addition to the angle of the bracket, another important design is the wind resistance design of the battery module, which mainly involves the design of the battery module rack and the wind resistance design of the light pole.

Finally, the solar street light controller, also known as the solar charge and discharge controller, is an automatic control system used in solar power generation systems to control the multi-channel solar array to power the battery and the battery to supply the solar inverter load. The choice of controller is also crucial.
